Kebutuhan energi listrik semakin meningkat seiring dengan perkembangan beban. Adanya perkembangan bebanmenyebabkan arus pada saluran transmisi semakin besar sehingga profil tegangan menurun dan losses semakin besar khususnya pada saluran transmisi 70 kV. Sehingga diperlukan cara untuk menanggulangi masalah tersebut yaitu dengan mempertinggi level tegangan atau voltage uprating dari 70 kV menjadi 150 kV. Penelitian ini dilakukan pada sistem 67 bus di regional Jawa Timur subsistem Paiton-Grati. Terdapat 20 saluran transmisi 70 kV yang akan di-uprating ke 150 kV. Pemodelan sistem dan simulasi aliran daya saat kondisi sebelum (Initial Condition) dan sesudah uprating (Uprating Condition) menggunakan software ETAP. Selanjutnya menganalisis aliran daya dan kualitas daya berdasarkan profil tegangan dan losses saluran transmisi dari masing-masing kondisi. Serta menggunakan performance index untuk membandingkan performa dari Initial dan Uprating Condition dimana terdiri dari Voltage Performance Index (PIV) dan Active Power Performance Index (PIMW). Rata-rata fluktuasi tegangan saat Initial Condition adalah sebesar -3.17%, dimana terjadi kenaikan profil tegangan saat Uprating Condition menjadi sebesar -2.24% dengan selisih sebesar 0.93%. Losses saluran transmisi saat Initial Condition sebesar 4.253%, dimana terjadi penurunan losses saat Uprating Condition menjadi sebesar 3.917%. Sehingga selisih losses saluran transmisi antara Initial dan Uprating Condition sebesar 0.336%. Performance Index saat Initial Condition sebesar 0.18535 sedangkan saat Uprating Condition sebesar 0.15658, sehingga Uprating Condition memiliki performa yang lebih baik

The substation is one of the components of the electric power system that is an important role in the distribution ofelectrical energy and load regulation. In the process of distributing electrical energy, continuity of good service is needed, but theinterferences still often occur, both internal and external. On Sunday, July 21, 2019 there was an interference, Lakarsantri feeder CB failed to trip so make the incoming 20kV CB trip. That interference was caused by the burning of the Switching Substation in the Citraland area. Therefore, a new relay setting is needed as a recommendation to use transformator 2 to avoid the recurrence of a similar fault. The relay settings have shown good results where the working time of the relay on the outgoing feeder side is faster than the incoming feeder 20kV and the incoming transformator 150kV side, when coordination simulated using the E-TAP 12.6.0 software by entering the current setting and the time setting, it shows good coordination because when there is an interference on the outgoing feeder, CB outgoing feeder works first, not the incoming feeder 20kV CB or the incoming transformator 150kV CB. Preventive maintenance on other equipment such as CB and CT need to be be done to increase of equipment reliability to reduce the occurs of protection failure or damage to the equipment.

Dalam menjaga kelangsungan penyalurannya di butuhkan perawatan rutin dan sistem pengaman yang bagus untukmengantisipasi keadaan yang tidak normal. Pada studi ini menganalisis gangguan petir di sepanjang saluran transmisi 70 kV dariGardu Induk Kebonagung menuju Gardu Induk Polehan dengan kondisi titik sambaran yang berbeda, serta menstudi kondisiperalatan ketika terjadi sambaran langsung di transmisi 70 kV. Dari hasil analisis ketika sambaran langsung pada kawat fasa sebesar 1098 kV menuju ke Gardu Induk Kebonagung, arrester akan bekerja membuang tegangan lebih ke tanah, maka tegangan petir yang sampai ke peralatan Gardu Induk Kebonagung kurang dari 60 kV sehingga peralatan di Gardu Induk Kebonagung terlindungi dari gangguan petir. Namun apabila arrester tidak bekerja ketika terjadi sambaran langsung, maka peralatan yang rusak adalah CVT (739,26 kV), Ds Line (545,56 kV) dan CT (378,274 kV), karena BIL peralatan tersebut lebih kecil daripada tegangan petir yang sampai dan mengakibatkan sistem padam. Ketika sambaran tidak langsung sebesar 97,068 kV menuju ke GI Kebonagung maka arrester akan bekerja dan peralatan di GI Kebonagung terlindungi. Namun apabila arrester tidak bekerja, peralatan tetap terlindungi karena CVT (65,347 kV), DS Line (16,95 kV) dan CT (4,230 kV), BIL masing-masing peralatan lebih tinggi daripada tegangan petir yang sampai. Maka dapat diketahui bahwa perlu adanya perawatan pada arrester agar dapat bekerja dengan baik ketika terjadi sambaran langsung serta perlu adanya pengecekan GSW dan nilai pentanahan pada tower agar nilai tegangan petir yang sampai di GI Kebonagung tidak lebih besar daripada ketika terjadi sambaran langsung.

High Voltage Air Line (in Indonesian known as SUTT) is defined as part of an electric power transmission network that is likely to be struck by lightning. This condition may lead to back flashover (BFO) phenomenon if the grounding value in the transmission is found to be high (>5 Ohms) and may also generate equipment failure. This research was intended to analyze the grounding improvement in tower T17, so that traveling-wave voltages may not result in failure of the main equipment at the substation, specifically the transformer. The value of the traveling wave at the substation was measured through simulation by means of the ATP Draw application in tower T17 to the substation. The grounding value may be reduced by increasing and widening the distance between the electrodes. The value obtained by modeling 4 electrodes with a distance of 0.5 meter was amounted to 1.73 Ohms. Furthermore, modeling 3 electrodes with a distance of 1 meter had successfully generated a value of 1.06 Ohm, and a value of 1.67 Ohm was also successfully obtained through modeling 2 electrodes with a distance of 2 meters. The ground resistance with a value of 67.05 Ohms that has not been repaired will lead to back flashover (BFO) caused by lightning strikes. However, this may be reduced properly with a lightning arrester which is capable of cutting the overvoltage at the substation, so that the voltage entering the transformer is below the BIL (Basic Insulation Level) value.

In maintaining the continuity of its distribution, routine maintenance and a good security system are needed to anticipate abnormal conditions. This study analyzes lightning disturbances along the 70 kV transmission line from the Kebonagung substation to the Polehan substation with different strike point conditions, as well as studies the condition of the equipment when a direct strike occurs in the 70 kV transmission. From the results of the analysis when a direct strike on the phase wire of 1098 kV goes to the Kebonagung Substation, the arrester will work to throw the overvoltage to the ground, so the lightning voltage that reaches the Kebonagung Substation equipment is less than 60 kV so that the equipment at the Kebonagung Substation is protected from disturbance lightning. However, if the arrester does not work when there is a direct strike, then the damaged equipment is CVT (739.26 kV), Ds Line (545.56 kV) and CT (378.274 kV), because the BIL of the equipment is smaller than the lightning voltage that reaches and causing the system to shut down. When an indirect strike of 97.068 kV goes to the Kebonagung substation, the arrester will work and the equipment at the Kebonagung substation is protected. However, if the arrester does not work, the equipment is still protected because the CVT (65.347 kV), DS Line (16.95 kV) and CT (4.230 kV), the BIL of each equipment is higher than the incoming lightning voltage.

In an electric power system, power quality is a major problem. One of the problems is load imbalance. According to IEEE (Institute of electrical and electronic engineer) number 446-1995 for load unbalance the limit value ranges from 5% to 20% on all phases. The monitoring panel system is useful for facilitating monitoring of power quality in real time so that the efficiency of electrical energy can be maintained. The object of this research is the load on Outgoing Transformer 2 at State Polytechnic of Malang. Measurements were carried out for 7 days. On Friday the average unbalanced load value is 6.75% with a neutral current of 34.4 A and conductor losses of 0.071 kW, while for 6 days it is classified as a balanced load with an average of 3.54-4.76% with neutral current of 10.5-24.6 A and conductor losses of 0.007-0.036 kW. So according to the IEEE standard std 446-1995 the Unbalance load value does not meet the standard on Friday, which exceeds the minimum standard of 5%. To get balanced loading results, it is necessary to carry out load balancing actions, namely by means of balancing. The recommendation for balancing is to move from phase R to phase S of 4.043 A and phase T of 2.695 A. After balancing, the % unbalanced load is obtained with an average of 3%, meaning that this load is classified as balanced with a neutral current of 13.44 A and losses conductor 0.014 kW.
